[U-Boot] [PATCH v2] imx: sys_proto: Add a prototype for board_mmc_get_env_dev()

[Diego Dorta]

When compiling with W=1 the following warning is observed:

board/freescale/mx6sabresd/mx6sabresd.c:266:5: warning:
no previous prototype for ‘board_mmc_get_env_dev’
[-Wmissing-prototypes] int board_mmc_get_env_dev(int devno)

Remove this warning by adding the function prototype into sys_proto.h file.

Changes since v1:
- Add 'mmc' prefix
- Change function prototype to sys_proto.h
- Update commit log accordingly
